本文给出隆尧台观测以来所记录的邢台老震区M≥4.5级地震和外围地区部分4.5级以上地震的电阻率异常图共十例。十次震例表明该台反映中强以上地震的重复性和灵敏性较好,中强地震前电阻率有较明显的异常变化。同时分析了该台所处的构造环境和台址电性条件,指出该台台址电性特征是其灵敏反映地震的重要条件。
In this paper, there are ten cases of resistivity anomalies recorded from the Longyao station, M≥4.5 earthquakes in the old earthquake area of Xingtai and some earthquakes above 4.5 in the peripheral areas. Ten earthquake cases show that the station reflects the repeatability and sensitivity of the above strong earthquakes is good, resistivity before the strong earthquake has obvious abnormal changes. At the same time, the tectonic environment and the electrical condition of the station are analyzed. It is pointed out that the electrical characteristics of the station are the important conditions for its sensitive reflection of earthquakes.
